haggler
A smelly, creepy person who follows you around like a stalker just to haggle you over something you didn’t even want.
"I watched you eat that candy. I know you want my gum drops.", A haggler in the bathroom
"You left your stink behind. I’m gonna get you for it.", A haggler at the mall
"You don’t know me, but I know your poop.", A haggler outside the school
